Title: Cooling capacity control for compression expansion refrigeration
IPC: F25B41/04
Filed: 1971-11-22
Abstract: 1363939 Refrigerating THERMO KING CORP 22 Nov 1971 [18 Jan 1971] 54124/71 Heading F4H The cooling capacity of a compression refrigeration system, e.g. for a refrigerated road or rail vehicle, is high enough to give a rapid initial cooling of a load and is then reduced by two separate controls. One consists of a variable valve 30 in the suction line 16 between the evaporator 15 and the compressor 10. This is controlled by a servo mechanism 31 activated by a pressure of refrigerant in line 33. A normally closed solenoid valve 34 in line 33 opens when thermostatic switch 35 closes. The valve 30 is then controlled by a temperature sensing coil 32 so that the suction pressure is varied to keep the load at the desired temperature. The other control is a by-pass 20 for the condensing coil 12, a valve 21 in the by-pass being controlled by a thermostatic switch 22. In operation, the system works initially at maximum capacity, valve 21 being closed and valve 30 open. When the temperature of the load has reached a given level the switches 22 and 35 will close, opening valves 21 and 34. Valve 21 passes hot refrigerant to the evaporator immediately reducing the cooling capacity of the system. Valve 34 activates the servo-valve 30 and the temperature is further reduced until the desired level is reached, sensing coil 32 then causing valve 30 to close and reduce the flow in the suction pipe 16.

Title: Improvements in or relating to aircraft flight control systems
Inventor: BARLTROP RICHARD KENNETH
IPC: B64C13/42
Filed: 1968-08-10
Abstract: 1,240,862. Aircraft control systems. ELLIOTT BROS. (LONDON) Ltd. Aug. 8, 1969 [Aug.10, 1968; Nov. 18, 1968], Nos. 38338/68 and 54483/68. Heading G3P. Each portion of a split control surface of an aircraft is positioned through a respective channel having a ram 11, servo-valve 13, valve-actuator 37 having output link 33, auto-control amplifier 39 and manual control linkages 25-31 with overload springbox 17. On auto-control, links 31 are locked by force limiters 21 such that links 29 transmit ram movements to common manual input linkage 49, 23; feedback in this case is from 43 (ram velocity) and 45 (ram position). A manually applied over-ride force will cause limiters 21 to release links 31 to permit manual control, with feedback via 31. Limiters 21 are also disengaged upon normal transfer from auto to manual control. To permit unavoidable obsynchronism between the position of any ram and the input linkage, each link 32 is restrained by a break-out spring 47 which yields in response to forces less than those required to disengage limiters 21. Pick-offs 53 associated with the springs 47 apply signals via integrators 55 to the amplifiers 39 to demand ram movement in a direction to null the signals; this improves synchronization. Runnaway of any signal ram drives the corresponding spring 47 on to its stop and eventually disengages limiter 21 to open a feedback through link 31 to stop the ram. Any prolonged yielding of a spring 47 can light a warning signal. The characteristics of springs 47 can be such as to yield under a given load, and thereafter permit maximum desynchronism with no further increase in load.

Title: Determining edge waviness for strip material
IPC: G01B11/24
Filed: 1972-11-29
Abstract: 1466658 Determining edge curvature of strip material METAL BOX Ltd 28 Feb 1974 [29 Nov 1972] 55052/72 Heading G1N A method for producing a signal representing the waviness of the edge of a strip of material moving longitudinally relative to the apparatus used, comprises generating signals representing the distance of the edge from a straight datum line at three positions spaced equally, close enough for the radius of curvature to be substantially constant between the two most separated positions, pro-  ducing an average of the signals from these two positions and deriving an output representing the difference between this average and the signal from the middle position. Three units, as 11, are spaced by the length, 1 metre, of the sheets to be cut from the strip. Edge followers, 15, which may also be wheels, are each held against edge 9 of strip 10 by piston-rod 16 of double-acting air cylinder 17, and its movement is measured by an inductive transducer feeding an integrated circuit operational amplifier with its core attached by piston 19 and plate 20 to rod 16 and its stator held by clamp 41 releasable for adjustment. Three setting plates, 43, rigidly secured to blocks 42 bearing pinch rollers 26, which may also extend the width of the strip, are mounted on a single plate 25, or on three plates, supported on an adjustable structure. Setting blocks 44 are prepared so that rods 16 are approximately at mid-stroke. Plates 43 and blocks 44 may be omitted. The outputs of the amplifiers of the most separated, detectors are connected by the ends of a potentiometer, whose tapping is adjusted to a potential proportional to the average of these transducer outputs and which is connected to a second potentiometer whose output is equal to this average. The difference of this output from the signal from the middle transducer is obtained from another operational amplifier, and passed to a meter and a pen recorder and could be used to stop the guillotine or strip motion or provide a print out of the percentage of strip outside a limit. An identical apparatus could be used for the other strip edge and the strip width thus measured. Non- contacting optical, inductive or capacative strip edge sensors may be used.

Abstract: 1,184,239. Container closures. M. B. STULL. 5 Dec., 1967 [29 Dec., 1966], No. 55370/67. Heading B8T. A container closure of moulded plastics comprises a tubular body 10 carrying by cooperating threads 24, 26 a screw cap 20, and having an axial discharge passage 14, the cap 20 being held captive by means of stop lugs 30, 32 on the outer surface of the upper end 16 of the body 10, 22 which abut against one or a plurality of stop lugs 34 on the internal surface of the cap 20. Lugs 30, 32 are stiffened by a transverse rib 36 which carries a closure pin 18 capable of sealing a discharge orifice 28 when the cap 20 is screwed down. Threads 24, 26 may be double to reduce the turning movement required in operation. Between the lugs 30, 32 and the threaded region 24 a cylindrical surface 38 of the body 22 is in contact with an internal annular sealing rib 40 on the cap 20. In a modification, Figs. 4-5 (not shown), the screw threads connecting cap and body themselves form a seal, no sealing rib being present. An additional stop lug on the internal wall of the cap rides on an external co-axial helical track around the lower end of the tubular body member, impinging on a lug at the upper end of the track to provide a second means of preventing complete removal of the cap. Again, Figs. 6-7 (not shown), the rib carrying the closure pin is located within the tubular body, which has a pair of sloping top edges, of the same pitch as the screw threads between cap and body, against which lugs on the internal surface of the cap slide.

In Fig. 3 the centrifugal weights have projections 84 which, below a predetermined speed, engage the ends of the pawls 58 to hold them disengaged from the ratchet wheel 62. When the speed exceeds the predetermined value the weights 70 pivot outwardly and the projections 84 release the pawls 58. The weights 70 carry pins 76 which engage diametrically opposed slots (82) in the plate 78. The two speed hub, Fig. 1, comprises a planet gear having input carried planet pinions 38 meshing a stationary sun gear 32 and a ring gear 40 fast with the pawl carrier 56. Below the predetermined speed a driving sprocket 16 fast with the planet carrier 36 is connected through a sleeve 44 and ratchet clutch 50, 52 with a driven drum 20 for direct-drive. Above the predetermined speed the pawls 58 are released and the driving sprocket drives the drum 20 through the planet gear and ratchet clutch 58, 62 for overdrive. In Fig. 11 the pawls 158 of the centrifugally controlled ratchet clutch are held disengaged from the ratchet wheel by a plate 178 which connects the centrifugal weights 170 for movement in unison. When the speed exceeds the predetermined value the weights 170 move outwardly and pins 176 thereon rotate the plate 178 to align apertures 188 therein with the pawls 158 which are thus permitted to engage with the ratchet wheel. In Fig. 13 three equally space centrifugal weights 270 are connected for movement in unison by a ring 278 which holds the pawls disengaged from the ratchet wheel when the speed is below the predetermined value. The centrifugal weights may be sintered mouldings or die castings.

Filed: 1968-11-27
Abstract: 1,214,196. Control of several motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 27 Nov., 1968, No. 56298/68. Heading H2J. In a system for preventing excessive slipping of the wheels of rail vehicles, driven by a plurality of electric motors 71, 72, a magnetic amplifier 2 provides a signal through delay network 31, 32, to a trigger 3 when the actual braking current falls below a reference value determined by the setting of a potentiometer 11. The output of the trigger 3 is applied to a timer 6 which delivers a signal through amplifier 4 to AND gate 10 for a predetermined period. If the slipping is severe, the signal from the timer 6 energizes contactor 5 which shunts the field winding 75 of the motor 71 by a resistor 77. The braking torque of the motor 71 is reduced to form a speed-difference between this motor and the others which are still slipping. Tachometer generators 81, 82 develop a signal through comparator network 83, 84, 85, to operate a trigger 9 which is associated with the timer 6 for maintaining energization of the contactor 5 as long as the speed-difference exceeds a predetermined value. As long as the contactor 5 is energized and a speed-difference exists, the gate 10 provides a signal to coil 12 and causes OR-gate 19 to de-energize coil 13 whereby the braking current is reduced. The coils 12, 13 actuate switching mechanism in the " running " and " braking " directions respectively, a braking controller 18 receiving a reference signal from the transmitter 1 for comparison with the actual value of the braking current.

Abstract: 1346043 Carrying liquefied gases BRIDGESTONE LIQUEFIED GAS CO Ltd 8 Dec 1972 [28 Dec 1971] 56643/72 Heading B7A [Also in Division F4] A tanker ship for carrying liquefied gases has a membrane tank 3 which is so arranged that the hull 1 of the ship does not need to support the tank for the latter's full height. The tank 3 is contained in a box 4, with the interposition of a compression resisting, thermally insulating layer 2. The bottom and side walls 4<SP>1</SP> and 4<SP>11</SP> of the box can maintain the tank structure in a given shape when it is unloaded but not when it is loaded. The curved part 3b of the tank is strong enough, because of its curvature, to resist the tank internal pressure so that the hull 1, which resists the pressure on the lower parts of the tank structure, need only extend up to the level of the bottom of the part 3b. The tank structure and the hull may be made separately and the tank then lowered into the hull.

Abstract: 1449279 Aroma and flavouring substances L GIVAUDAN & CIE SA 17 Dec 1973 [18 Dec 1972] 58281/73 Heading A2B Aromas and flavourings are made by treating (e.g. for 15 mins. to 2 hrs.) to non- enzymatic browning temperatures (e.g. 90- 180‹C) a liquid product (which may be in spray-dried form) obtained from full cream milk, skim milk, skim milk powder, milk concentrate, whey, whey powder, yoghurt, yoghurt powder or buttermilk, by enzymatic proteolysis and lactic acid fermentation (or in the case of yoghurt or yoghurt powder by enzymatic proteolysis only). The proteolysis is carried out using proteases of vegetable, animal or microbial origin which are capable of clarifying aqueous suspensions in less than 24 hours in weakly acid, weakly basic or neutral medium, and the lactic acid fermentation is carried out using bacteria of the genus Lactobacilli or Streptococci. The heating step may be carried out in the presence of cysteine, in which case a meaty aroma is produced, the cysteine being used in a ratio of 1:3 to 1:4 of liquid product. If less or no cysteine is used, a baked goods aroma is formed. Apart from cysteine, other amino acids or peptides (e.g. alanine, arginine, cystine, proline, glycine, histidine, isoleucine, leucine, lysine, serine, threonine, valine, anserine), sugars (e.g. arobinose, xylose), polyalcohols (e.g. glycerol, propylene glycol), monosodium glutamate, disodium inosine-5'-monophosphate, disodium guanosine-5-phosphate, fats (e.g. groundnut oil) butter or butter substitute, may also be included. The aroma may be used in solution, or as a paste or powder. A carrier e.g. gum arabic, salts, or brewers yeast may be used. Indoles, maltol, dienals, spice oleoresins or smoke aromas may also be added as flavour improvers.

Abstract: 1416556 Electrostatic separation COMMISSARIAT A L'ENERGIE ATOMIQUE 18 Dec 1972 [31 Dec 1971] 58319/72 Heading B2J [Also in Division G1] An electrostatic precipitator comprises a chamber 2 provided with plate electrodes 4, 6 between which a direct potential V1 is applied; an inlet duct 10 which merges into the chamber 2 with a conical configuration 12 which, together with the provision of a honeycomb structure 24 and grids 22, ensures that gas flows smoothly without turbulence from the duct 10 into the chamber 2; and a conduit 16 provided with an ioniser 20 and an outlet 18. In use, polluted gas containing suspended particles which have been charged by the ioniser 20 is injected by way of the conduit 16 and an outlet 18 into a non-turbulent flow of "clean" gas supplied from the duct 10. The charge acquired by each particle is dependent upon its size, and as the flow through chamber 2 is non- turbulent, each particle is attracted to the collector plate 4 to a greater or lesser extent in accordance with its size. Thus larger particles are collected on the plate 4 during the earlier part of the passage of the polluted gas through the chamber 2 and smaller particles during the later part of the passage. Accordingly, particles graded as a function of their size can be collected on the plate 4 for later quantitative and qualitative analysis. A further electrostatic precipitator 28 may be provided to collect any particles, which will be uncharged, in the gas supplied through the duct 10. Thus, if the pollution of atmospheric air is to be investigated, this air is supplied both to the duct 10 and the conduit 16, the particles in the former being collected generally in the precipitator 28 and the particles in the latter, which have been charged by the ioniser 20, being collected as a function of their size in the chamber 2. A modified precipitator is described with refereence to Fig. 3 (not shown). The ioniser 20 is energised from both A.C and D.C sources, a suitable construction being described with reference to Fig. 2 (not shown).
